Answer this question truthfully
### Question: What causes Cerebral hypoxia?
### Response: In cerebral hypoxia, sometimes only the oxygen supply is interrupted. This can be caused by:
Breathing in smoke (smoke inhalation), such as during a fire Carbon monoxide poisoning Choking Diseases that prevent movement (paralysis) of the breathing muscles, such as amyotrophic lateral sclerosis (ALS) High altitudes Pressure on (compression) the windpipe (trachea) Strangulation
In other cases, both oxygen and nutrient supply are stopped, caused by:
Cardiac arrest (when the heart stops pumping) Cardiac arrhythmia Complications of general anesthesia Drowning Drug overdose Injuries to a newborn that occurred before, during, or soon after birth (cerebral palsy) Stroke Very low blood pressure
Brain cells are extremely sensitive to a lack of oxygen. Some brain cells start dying less than 5 minutes after their oxygen supply disappears. As a result, brain hypoxia can rapidly cause severe brain damage or death.
